From: Omar Sandoval <osan...@fb.com> I came across my ancient RCU string branch [1] and decided to revive it and finally put it to rest. In the process of checking it with sparse, I found a handful of other issues.
Patch 1 should probably go in 4.13, as it fixes bugs introduced this cycle by the conversion to blk_status_t. Patch 2 is an old bug, so it could wait for 4.14 but it might as well go in for 4.13. Patches 3-5 are the RCU string series. Patches 6 and 7 are minor cleanups found by sparse. Patches 3-7 can wait for 4.14 or 4.15. Based on 4.13-rc6.
